Body composition estimations by BIA versus anthropometric equations in body builders and other power athletes.

摘要: Background. Two main questions are stated: 1) BIA and anthropometric equations accurate in estimating body composition male power athletes more specifically builders 2) is there a difference when compared to weight lifters? Methods. Experimental design: this descriptive, comparative study on selected sample of athletes. Participants: 49 Belgian elite sub-top (34 15 lifters) were included sample. More than 70% was preparation competition at time data collection. Measures: an extended set measures taken. Body estimated by (Bioelectrical Impedance Analysis) regression skinfolds. Somatotype muscle+bone areas calculated. Factor analysis all carried out determine the structure Results. Compared external visual criteria, Durnin Womersley Lohman (skinfolds) Guo-equation (BIA) only that could accurately estimate for specific group However, sum skinfolds attains most subcutaneous fatness. have significantly (p<0.01) larger arm thigh circumferences mesomorfic other (5.9 vs 3.8). Conclusions. This shows extreme not as equations. Moreover, preferred prediction In addition, muscular leaner
